This has most probably something to do with the SSL Error discussed in other threads. Do you have more message lines from you log for us?

I am experiencing the same with my workunit too, though I am getting work from other projects and they all appear fine.

I've been getting the same thing. I got it a few times yesterday and then it finally went through. Then it's started again this morning at around 5am and still unable to connect. It must be with just DDDT because I was doing RICE up until yesterday with no problems.

Looks like it is back up as of 8:36am. I just got a successful download.

rice is affected too. i saw 2 ddt and 1 rice that didnt upload when i woke up this morning. i decided to turn off my PC for an hour since i've been crunching seti on my 8500gt for several days. when i started boinc again, the 2 ddt and 1 rice changed from "uploading" to "computation error". i've been experiencing upload problems with seti too but they didnt turn into computation errors.
